New Technology of Fertilizer in China

China
has developed into the world's largest manufacturer and consumer of fertilisers.
After all, the Middle Kingdom uses more than a third of the world's fertilisers
available, which is equivalent to the combined consumption of the USA and
India. China is in heavy need of fertilisers to satisfy its growing demand for
crops and other agricultural products.

According
to CCM, China uses 40% of its fertilisers on cereal crops, while another 33% is
used for fruits and vegetables. The biggest challenge that the country faces is
the feeding of its 1.4 billion population with only about 8% arable land.
Hence, chemical fertilisers are developed and produced heavily to boost crop
yields and scale up agricultural production. The excessive use of chemical
fertilisers, however, is raising environmental and food safety concerns.

China’s
fertiliser industry is facing both serious problems and new development
opportunities. serious oversupply, cutting excess capacity has been a
consensus. Currently, domestic fertilizer capacity has reached 200 million MT.
Along with the pressure from policies, reducing the use of fertilizer has
become inevitable.

Alongside
the rising fertiliser output, the production technology in China has also
evolved throughout the past years. Market intelligence firm CCM analysis the
most common production methods and gives insights into China’s overall
fertiliser production.

There
are various production technologies of compound fertilizer in China, with
granulation as the key process in production. According to maturity and application
degree of process, it can be classified into slurry-spraying, melt spray
granulation, tower melting spraying granulation and rotary drum ammoniation
granulation process.

Restricted
by production scale and number of products, the slurry-spraying process is
adopted by only a few enterprises. With similar theory, melt spray granulation
and tower melting spraying granulation are widely used, the difference is that
tower granulator and related equipment are introduced into tower granulation.

At
present, dozens of enterprises in China have adopted this process. Ammoniation
and secondary dechlorination are adopted in the rotary drum ammoniation
granulation. Granulation equipment like coating and disc granulator is also
adopted. New compound fertilizer technologies aimed at improving the
utilization rate of fertilizer by adding some kind of additives or nutrient
elements, increasing the effect of fertilizer, making multifunctional
fertilizer or by slow release technology and water-soluble fertilizer
technology.

The
report is dedicated to helping companies find the solution to lower the
production costs and increase production efficiency of some kind of
fertilisers, through technology investigation of producers, universities, and
research institutes in China. Key targets include urea, ammonia, slow release
fertiliser, stabilised fertiliser, compound fertiliser, and water-soluble
fertiliser.
